What is yttrium?
Yttrium is a chemical element with the chemical symbol Y and atomic number 39 in the periodic table of elements. It was discovered in 1794 by the Swedish chemist Carl Gustaf Mosander. It belongs to the rare earth group and is considered a metal in the periodic table. Yttrium is a silvery, soft, ductile and malleable metal. It is also resistant to chemical corrosion, as it forms a protective oxide layer on the surface when exposed to air. It has many unique chemical properties that are used in a variety of industrial applications, including metal alloy production, catalysis, electronics and nuclear chemistry.
Yttrium is often used as a catalyst in chemical reactions, as it can help speed up reactions without running out. In addition to its chemical properties, yttrium also has unique physical properties. Its atomic mass is approximately 88.9 g. mol and its atomic nucleus contains 39 protons and 50 to 64 neutrons, depending on the isotope. The most stable isotopes of yttrium are Y-89 and Y-91, which have half-lives of about 16h and 58 days, respectively.
However, some isotopes of yttrium are radioactive and decay by nuclear fission. Yttrium is often used in the production of other chemical elements. For example, it is a component of yttrium oxide Y2O3, which is used as an additive in ceramics, glazes and paints. It is also used to produce metal alloys such as stainless steel, aluminum and magnesium. Yttrium is also present in rare earths, making it an important element in the production of these metals.
Yttrium is an important chemical element with unique properties, used in a variety of industrial applications. Physicists and chemists are particularly interested in yttrium for their research because of its quantum properties and its applications in pure and applied chemistry.
